Sounds as though you've really loaded up on the soilless mixes! Potting soil contains organic matter and sand along with perlite to help with drainage. Pine mulch is basically partially decomposed pine needles but it has a little more bulk than the potting soil. Likewise with the rest of the products. You can grow your vegetables in any or all of the organic products you have purchased. I use straight potting soil but you can mix your organic materials in equal parts by volume and/or you can add an equal amount of garden soil to any or all of the organic materials. By adding organic matter you ensure that the soil will drain quickly yet hold just the right amount of moisture for the roots of your plants. Best wishes with your veggies.
